How to Secure Your Account with Two-Factor Authentication (2FA)

Two-factor authentication (2FA) adds an extra layer of security by requiring two forms of verification before account access or certain transactions. Understanding authentication factors, setup, precautions and recovery can help protect personal and financial information.

• 2FA combines two different authentication factors, such as a password and OTP, to strengthen account security.
• It can help reduce risks associated with unauthorised access, phishing, identity theft and compromised credentials.
• Set up 2FA through your account’s authorised security settings and complete the required verification steps.
• Keep passwords, PINs, OTPs, devices and recovery details secure, and avoid unverified authentication requests.
• If you lose access to your 2FA method, use the service’s authorised recovery process or support channel.

Two-factor authentication (2FA) is a security method that requires two different forms of verification before you can access an account or complete certain transactions. It adds an extra layer of protection beyond a password or single credential. Each factor verifies your identity differently, making unauthorised access more difficult if one credential is compromised. The authentication methods used can vary depending on the service and its security process.

The two authentication factors can include:

• Something you know: A password, PIN or passcode known only to you.
• Something you have: A registered mobile device, security token or other trusted device in your possession.
• Something you are: A biometric characteristic, such as a fingerprint or facial recognition.

For example, a service may require you to enter a password and then verify your identity using an OTP sent to your registered mobile number. Keeping both factors secure can help protect your account from unauthorised access.

How does two-factor authentication help?

Two-factor authentication helps strengthen account security by requiring an additional verification step during access. A person who obtains one login credential may still need the second authentication factor to gain access.

This additional layer can help reduce the risk associated with several types of digital security threats:

• Unauthorised access: A second authentication factor makes access more difficult when only one credential is known.
• Phishing: If a password is disclosed through a phishing attempt, another verification factor can provide an additional security layer.
• Identity theft: Additional authentication can make it harder for another person to access an account by impersonating the account holder.
• Exposure of personal information: Digital financial accounts may contain sensitive personal and financial information that needs to be protected.

Two-factor authentication does not remove every security risk. You should continue to protect your login credentials and avoid responding to unverified requests for confidential information.

How do you set up two-factor authentication (2FA)?

Setting up two-factor authentication (2FA) involves enabling the security feature through the authorised account settings and completing the required verification steps. The exact process may vary depending on the service and the authentication methods it supports.

1. Open your account settings: Sign in through the authorised platform and look for the security or authentication settings.
2. Select 2FA: Choose the option to enable two-factor authentication for your account.
3. Choose an authentication method: Select from the verification methods supported by the service, such as an OTP, authentication app, security key or biometric verification.
4. Complete verification: Follow the on-screen instructions and provide the requested verification details.
5. Confirm 2FA activation: Complete the final verification step to enable 2FA on your account.
6. Store recovery details securely: If recovery codes or similar backup options are provided, keep them in a secure place and do not share them with anyone.

Once 2FA is enabled, you may need to complete an additional verification step when accessing your account or performing certain transactions. Keep your authentication details private and use only authorised channels to manage your account security.

Two-factor authentication is particularly relevant to financial accounts because they can contain sensitive personal information and provide access to financial services. An additional authentication layer can help reduce the risk of unauthorised access to this information. Digital financial services may involve activities such as viewing account information, managing payments and accessing other financial services. Protecting access to these services therefore requires careful handling of authentication credentials.

Using 2FA can support account security in the following ways:

2FA should be combined with basic security practices, such as keeping your MPIN and OTP confidential and using only verified channels to access your account.

What precautions should you take when using 2FA?

Using two-factor authentication (2FA) can add an extra layer of account security, but you should also protect the credentials and devices used for verification.

• Keep OTPs private: Never share one-time passwords (OTPs) with anyone, even if they claim to represent the service.
• Protect your login details: Keep your passwords, PINs and other authentication credentials confidential.
• Use authorised channels: Access your account only through the official website, app or other authorised platform.
• Secure your device: Use a screen lock and keep your device and security software updated.
• Check login requests: Do not approve unexpected authentication requests or verification prompts.
• Protect recovery details: Store backup codes and recovery information securely and do not share them with others.
• Report suspicious activity: Contact the relevant service through its official support channel if you notice unusual login attempts or account activity.

Following these precautions can help you use 2FA more securely and reduce the risk of unauthorised account access. Review your security settings regularly and keep your authentication details protected.

Who can use two-factor authentication?

Two-factor authentication (2FA) can generally be used by people who have an account with a service that supports this security feature. It may be available for personal, financial, email, social media and other online accounts, depending on the service provider. Users typically need access to the verification method supported by the service, such as a registered mobile number, authentication app, security key or biometric method. The availability and setup process can vary between platforms, so check the account's security settings for the available options. Some services may enable 2FA by default, while others allow users to activate it manually. If 2FA is available, follow the service provider's authorised setup process and keep your authentication details private. Using 2FA can add an additional layer of protection against unauthorised access to your account.
